Firearm Involvement in Delinquent Youth and Collateral Consequences in Young Adulthood: A Prospective Longitudinal Study, Chicago, Illinois, 1995-1998

This study contains data from the Northwestern Juvenile Project (NJP) series, a prospective longitudinal study of the mental health needs and outcomes of youth in detention. This study examined the following goals: (1) firearm involvement (access, ownership, and use) during adolescence and young adulthood; (2) perpetration of firearm violence over time; and (3) patterns of firearm victimization (injury and mortality) over time. This study addressed the association between early involvement with firearms and firearm-firearm perpetration and victimization in adulthood. The original sample included 1,829 randomly selected youth, 1,172 males and 657 females, then 10 to 18 years old, enrolled in the study as they entered the Cook County Juvenile Temporary Detention Center from 1995 to 1998. Among the sample were 1,005 African Americans, 524 Hispanics, and 296 non-Hispanic white respondents. Participants were tracked from the time they left detention. Re-interviews were conducted regardless of where respondents were living when their follow-up interview was due: in the community, correctional settings, or by telephone if they lived farther than two hours from Chicago.

本研究收录了西北青少年项目（NJP）系列数据，该系列数据为前瞻性纵向研究，旨在探讨被拘留青少年心理健康需求及其结果。研究旨在实现以下目标：（1）青少年及年轻成人期间的枪械涉入（获取、拥有和使用）；（2）随时间推移的枪械暴力行为；以及（3）随时间推移的枪械受害者模式（伤害和死亡率）。本研究探讨了早期涉入枪械与成年期枪械暴力行为及受害者之间的关联。原始样本包括1,829名随机选取的青少年，其中男性1,172名，女性657名，年龄在10至18岁之间，他们于1995年至1998年间进入库克县青少年临时拘留中心时被纳入研究。样本中包括1,005名非裔美国人，524名西班牙裔和296名非西班牙裔白人受访者。参与者从离开拘留所开始被追踪。无论受访者跟进访谈时居住地点为何——社区、矫正设施或距离芝加哥超过两小时的地方，都会进行重新访谈。
